Pneumatic Revolver

 Hello, I've been coming to Instructables for a while now but I just made an account. Anyways, I've been trying to brainstorm an idea for a PVC Revolver. Does anyone want to give this a try and post your results? I might try if I can get to the hardware store this weekend.

Getting my comp to see my arduino uno clone ? The same ol windows route shown everywhere aint werkin'!!?

XP pro -sp3 -  ...I've tried installing the official USB2.0 driver, I've  tried the Virtual com port and the FTDI  drivers from the official sites...NOTHIN'!! I keep getting FOUND NEW HARDWARE -USB2.0-SERIAL...I go through all the steps found everywhere on how to "normally" get the comp and UNO to show up in sys' properties and hardware profiles etc etc....problem is I dont get any of the results nor devices these how-tos are showing. I know my way around a comp and windows...I'm just not getting past the NEW HARDWARE USB2.0  issue..let alone even seeing UNO as a device. The virtual port drivers dont do anything at all...no more ports show up, no option to create one.... I've installed the arduino drivers incl. USB and the UNO drivers...no love either I've uninstalled and installed in the root dir. ..no luck.. I even changed the ATmega from the 8A it came with to a ATm328 w/ bootloader and blink sketch already installed on  my Arduino as well. ANYONE have this issue that has found a solution?.... other than throwing my comp out the window and using the UNOs as fancy paper weights?

Book cover Hinge

Hey all. First time poster here (second attempt, since Instructables stopped responding the first time) so hopefully I am posting in the appropriate place. I have in mind a leather-book-style cover for my tablet that I'm very excited to work on. However, I would like to use friction or torque hinges to position the cover at any angle  from the spine in a 180 degree radius and have it stay there, similar to the screen of a laptop rotating around the hinge. I've included a picture that shows the basic design that I'm aiming for, though the hinge itself doesn't need to be ornate. Unfortunately, I don't really know where to find such a thing. I've looked on various furniture hardware sites and taken a trip to the local hardware/home improvement stores, but I haven't found anything that matches what I'm looking for. Common small brass butt hinges would be ideal if they had friction/torque properties to them, but I can't seem to find anything like that. I've never looked for specific hinges before though, so for all I know they've been right in front of my and I didn't realize what they were. Does anyone know where I can find such hinges, or can someone offer up an alternative solution? Perhaps there is a way to add friction to simple hinges bought from a hardware store. Thanks in advance for pointers/advice.

Why can't Instructables do away with the "removed by author or blah blah blah" thing. It just clutters things up, and doesn't really serve a purpose. If instructables wants the person that made the comment to know it was removed, email them. Any time we have to remove something that can't be edited, it leaves behind this garbage. Before, there was a set rhyme and reason to deleting posts and not having that happen (bottoms up!), but recently I created a post which was the first reply to the first comment in my $1 security hardware instructable, and noticed a glaring error in it and IMMEDIATELY deleted it (because there was no EDIT function) and it left one of these steaming piles of Yak poo in the comment thread.

Assuming I have the the means to obtain the required materials Pommel horse revisited: Assuming that hardware can be obtained, i.e, the core,  be circular tubing, solid steel or wood core, hallow construction( example, think of a construction a post using 4 2' x 4', ergo a hallow post),  pommel handles, the polyethylene foam, the vinyl or leather covering, the leg supports, be they wood, square or circular tubing, and the necessary tools ( wood/welding) how is a pommel horse made to closely match a regulation pommel horse http://visual.merriam-webster.com/sports-games/gymnastics/gymnastics/pommel-horse.php(not a trainer)? Answers should include the following:  Feel free to add to this list as I am sure it isn't complete in your answer. Construction materials and hardware used to construct the pommel horse, aside from the aforementioned basics. i.e, use of a solid core like 4 8'x8' posts, a circular tube, or variations to achieve the desired dimensions/ If the design includes the bread loaf taper, how was this achieved? How the pommels were attached and the hardware used.    If the pommels are fabricated how was this done, but lets assume they will be purchased. Variations of supporting base structure is acceptable. Answers need to include how supporting base is attached to the horse and what hardware or means of attachment are used.     A. If leg supports are adjustable, by way of circular tubing or square tubing with holes that can be locked into place, are they prefabricated?      a1. How were the adjustable height leg supports constructed. For example, Think of sliding a smaller pipe into lager one, or square tubing for that matter.        a2.

If legs or wood and adjustable, how is this achieved and by what means, for instance, drilled holes and wooden dowels or longboats, etc...      Thanks to all those who dive into this.

Old Phone That Can Play Games? Ideas...

Hi guys, so I was recently talking with my friend Omar about random stuff, and (like always) our conversation somehow got really off track and we ventured into the history of old phones (Nokia 3310...breaking everything we touch since 2000). We somehow got to thinking about how old bar style phones could be useful for the making community. My thought (which I incidentally shouted out as loud as a human can go) was this: what if we could put a really basic game onto the phone? Would it be possible with the current hardware? Maybe...and the controls are there, most phones have a D-pad with 12 keys (which could be special function keys in the game). I was thinking of games along the line of Doom, or any old FPS game...but in retrospect, that would be ambitious, and to be practical, a stick man game would probably be the minimum.  So my questions are: a) would it be possible for the hardware on the phone to be wiped of all software and would it be good enough to support the code. b) is it even possible to reprogram the phone, or even get some sort of bootloader onto the device? Probably not. And if not, is there any other way to put a game or any file onto the phone's hardware... I guess that's it. In general, would it be possible, and if yes, could anybody give me a few starters so I could try to do it? Thanks, Ivan

I have an Arduino Duemilanove and a 16x16 led matrix with no driver IC.  I think I understand the basic hardware principles of multiplexing an array. It should be theoretically possible as long as I use an external system to controll half of the pins. So far I have the hardware about half done. I have some chips set up to sweep through the positive end of the rows of LEDs. I've made this by daisy chaining two 4017s together with two AND gates. This gives me a series of pins that light up by turns up to 16 with some skipped steps at 10 and 16. I got the info from here: http://www.circuitdb.com/circuits/id/154 THE QUESTION IS: Where do I go from here? I'm trying to learn how to program by doing this project.
